Method Summary

void	enterState(java.lang.String state, StateMachine context) This method is called by the state machine when it is enters a new state
void	executing(java.lang.String transition, StateMachine context) This method is called whenever, the state machine is executing a transition.
void	leaveState(java.lang.String state, StateMachine context) This method is called by the state machine when it is leaving the current state
void	propertyChanged(java.lang.String name, java.lang.Object value, StateMachine context) This method is changed whenever a state machine property is changed.

Method Detail

leaveState

void leaveState(java.lang.String state,
                StateMachine context)

This method is called by the state machine when it is leaving the current state
